Remote controlled echocardiography
”Second Generation” Telemedicine
• Support demanding distance investigations
• Achieve high communication quality
• Create a module based communication environment,
• Utilize the broadband potentials
• Utilize standard desktop computers
• Access patient information directly in the telemedicine situation
• Combine synchronous and asynchronous communication
• Support regional development:•- move knowledge to the patient•- “export” top expertise services to other regions
The general background in Northern Sweden:
• Long distances.
• Expensive transports.
• Limited access to cardiac expertise
• More elderly people will need health care, nursing and rehabilitation.
• New kinds of hospitals, smaller but more specialized towards acute treatment.
The general background in Northern Sweden:
• Increased preventive and knowledge-based health care.
• More physically and mentally active people in high age will be found among patients and their relatives.
• An increased usage of IT within health care itself.
• More treatment and rehabilitation of patients at their homes.
Congestive Heart failure (CHF)Background:
• CHF is the only cardiovascular condition in which both the prevalence and the incidence continue to rise1
• CHF is the leading cause of hospitalisation amongst the >65 year age group3
• Annual inpatient and outpatient expenditure on CHF in Sweden has been estimated at SEK 2.6 billion2

• Correct diagnosis.
• Early diagnosis
• Optimal treatment
• Managed care
• Follow-up of selected patients.
• Improved prognosis
• Lower cost

Project developement
2001: Clinical and scientific cooperation with primary health care.
2002: Echocardiography with portable echomachine and consultation at the
primary
health care center.
2003: Echocardiography with portable echomachine and consultation through
telemedicine as a videoconference.
2004: Remoted-controlled echocardiography and consultation using broadband
and Internet
2005: Clinical tests in daily care at rural health care centers

*A transducer is an electronic device that converts energy from one form to another. It is a small, hand-held device attached to the scanner by a cord. The sonographer presses the transducer firmly against the patients skin to obtain images.

The Goals:
• Shortening time to diagnosis
• Saving money for Health Care System
• Easing agony and suffering for patients
• Obtain technical clarification
• Diagnose 30 patients in daily care using standard level communication technology (H 323 platform 5-10 Mbit)
• Diagnose 30 patients in daily care using high level communication technology (Confero system 20-40 Mbit)

Performed and planned tests
Possible applications of remote-controlled echocardiography :
-Clinical:
-Telemedical consultations in remote areas
- Ergonomy for sonographers
-Special areas- dangerous areas: war and emergency situations, - chemical and bacterilogical poisoned areas,- radiation poisoned areas
Ready to go!!
